The infrastructure that registers and distributes Crossref metadata has been running and growing for more than two decades. It now does considerably more than it was built to do, and it shows: two large, tightly coupled monoliths (Content System and REST API), where a change in one place risks breaking something in another.
In December 2026, we plan to publish new Crossref Member Practices which will set out the standards we expect all Crossref members to meet. From August to October 2026 we are consulting with our members on a draft of these Member Practices. This blog provides the background to this, and explains how you can share your views.
The Crossref community in India is as diverse as the region that it represents, comprising 1605 members, 11 sponsoring organisations, and 5 ambassadors, who between them cover the length and breadth of this country. Between November 2025 and March 2026, we organised three webinars focused on supporting this community with best metadata and publishing practices. We collaborated with the Directory of Open Access Journals (DOAJ) and the Committee on Publication Ethics (COPE) to embed understanding of metadata’s role in the greater context of publishing integrity.
PID strategies are being written around the world right now, and the decisions being made will shape the scholarly record for decades. After 25 years running open scholarly infrastructure—now on behalf of 25,000 members in 167 countries—Crossref has an informed perspective on what those decisions should ideally rest on. Today we’re setting it out in our first position paper: Persistent identifiers in research infrastructure policy: the need for a holistic approach. You can read it online or download the PDF; it’s a 16-minute read.
Registering your DOI records using OJS version 3.4
You can register your DOI records with us using the OJS (Open Journal Systems) platform by enabling the Crossref Manager plugin. We highly recommend including your references in the metadata you send to us, too - you can do this by adding the OJS references plugin. The instructions below are for configuring OJS version 3.4 (more in Public Knowledge Project’s (PKP) documentation).
As Journal Manager, under Settings, click Website > Plugins.
Under Installed Plugins, scroll down to the section labelled Generic Plugins.
Click the checkbox next to the plugin description to enable the plugin.
Step 2: Setting up automatic DOI registrations in OJS 3.4
Go to the Distribution menu
Select the DOI tab
Click on the Setup option
Check the box to allow DOIs to be assigned to your published works
Check the box to determine which items DOI will be assigned
Enter your Crossref assigned DOI prefix. Your prefix will start with 10. and is in the format 10.xxxx (e.g., 10.5555).
Select your preferred stage for automatic DOI assignment to your articles (can be upon the article reaching copyediting stage or upon article publication).
Select your preferred method of DOI suffix generation (can be Default, None for manual entry of suffixes, or Custom pattern)
Next, switch to the ‘Registration’ tab menu
Select Crossref your ‘Registration Agency’ from the drop down options. If you don’t see “Crossref” in the list, navigate to Website > Plugins > Plugin Gallery to enable the ‘Crossref Manager Plugin’.
Check the box under ‘Automatic Deposit’ to enable automatic DOI deposits from your OJS instance.
Enter your name here as the depositor.
Enter your email here as the depositor (all deposit emails will be sent to this email).
Enter your assigned Crossref username. For example support@crossref.org/abcd
Note: if the combination of username and password is incorrect, OJS will return a ‘401 unauthorized status code’ error at the time of registration. This error indicates that the username and password are incorrectly entered. That is, they do not match the username and/or password set with Crossref.
If you are using organisation-wide, shared role credentials (i.e. your username is a collection of letters), you can simply add in your shared username and password.
If you are using personal user credentials that are unique to you (i.e. your username is your email address), you’ll need to add your email address and your role into the username field, and your personal password into the password field. Here’s an example of what this will look like:
Enter your set personal password into the password field.
IMPORTANT: Leave the test checkbox unchecked.
Step 3: Activate the OJS references plugin
The OJS references plugin is available from OJS 3.1.2 onwards. The plugin will use the Crossref API to check against plain text references and locate possible DOIs for articles. The plugin will also allow the display of reference lists on the article landing page in OJS and deposit them as part of your metadata deposit. Linking references is a requirement of Crossref membership.
Workflow Settings
Click ‘Settings’ and then ‘Workflow’ from your dashboard
Under the ‘Submission’ tab, choose ‘Metadata’!
Scroll down to the bottom and find the ‘References’ section
Make sure you enable references metadata by clicking the checkbox ‘Enable references metadata’. You also need to select the option ‘Ask the author to provide references during submission’.
Click save!
Website Settings
Then you need to activate the references plugin on the website, too, by following the instructions here:
Click ‘Settings’ and then ‘Website’ from your dashboard
Choose the ‘Plugins’ tab.
Search ‘Crossref reference linking’
Click the ‘Crossref reference linking’ checkbox
This plugin will deposit the references that you enter into the XML deposit.
Additional OJS plugins for Crossref
In addition to the Crossref XML plugin for OJS, there are also other important plugins that can be enabled in OJS to enrich your metadata records:
Funding Metadata plugin - as of OJS 3.1.2, it is possible to enable a funder registry plugin for submitting funding information to Crossref. The plugin will use the Open Funder Registry to check against existing funding agencies. The plugin will include funding information in your Crossref DOI deposits.
Similarity Check plugin - if you are using OJS 3.1.2 or above, you are able to use the Similarity Check plugin. This will enable you to automatically send manuscripts to your iThenticate account to check their similarity to already published content. You will need to be subscribed to Crossref’s Similarity Check service for this to work.
ROR plugin - the ROR Plugin for OJS enables authors to add the ROR ID for the organization they are affiliated with.
Getting help with OJS plugins
The team at Crossref didn’t create these plugins - they were either created by the team at PKP, or by third-party developers. Because of this, we aren’t able to give in-depth help or troubleshooting on problems with these plugins.
